Abstract: Aliphatic aldehydes were found during the combustion of materials.Tobacco smoke contains aldehydes.Fire fighters were exposed to aldehydes when they conducted firefighting.Aldehydes in ambient air come mainly from the incomplete combustion of hydrocarbons and from photochemical reaction.Most aldehydes in ambient air are formaldehyde and acetaldehyde.Formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, and benzaldehyde were found in the atmosphere in Los Angeles.Burning Chinese incense for worshipping deities is a Chinese daily routine.It was suspected to be a factor causing nasopharynegeal cancer.Epidemiological studies correlated it with the high risk of childhood brain tumor and the high risk of childhood leukemia.Ames test identified the mutagenic effect of the smoke from burning Chinese incense.The smoke had bee proved to contain polycyclic aromatic hydrocarbons and aromatic aldehydes.Suspicion about formaldehyde and other alphatic aldehydes was evoked, when a survey of indoor air pollution was conducted in Taipei city.This study determined the presence of aliphatic aldehydes in the smoke from burning Chinese incense under a controlled atmosphere.12 refs., 5 figs., 2 tabs.
